5 Mount St. Helens
4/23/23
May 18, 1980. Washington state's Mount St. Helens erupts, obliterating 200 homes, 230 square miles of roads and wilderness, and claiming nearly 60 lives. Since 1978, scientists had warned that the volcano was overdue for an eruption, so how did it catch everyone by surprise? Through expert testimony from geologists, local reporters, and residents, we revisit the most destructive volcanic event in U.S. history and reveal ten failures that escalated the catastrophe, including ignored warnings, inadequate safety zones, and poor rescue planning.
